You will have to configure postfix to use a relay host

relayhost = [gateway.example.com]

Or

relayhost = 192.168.1.50

You can find detailed instructions in /etc/postfix/main.cf or follow this link

http://www.postfix.org/postconf.5.html

Thankyou Very Much i have bad configuration.

Thanks

The old and hated Trixbox had a configuration page for this.

I just changed the postfix main.cf file and added relayhost=[smtp.cox.com] and works fine afterwards
